Weapon Description:

The Bashaak is a two meter wooden staff with clubbed ends. This weapon has its origin in isolated rain forests where hardwoods are common. They are often used by more isolated and savage populations. These staves are perfectly balanced and usually crafted by the user, however growing demand by every-day adventurers has lead weapon-smiths to begin making standardized versions. Bashaaks can the used used as two-handed weapons or double weapons depending on the users preferred fighting style (two-handed for strength oriented styles and double for dexterity oriented styles).
Metal variants and variants of other materials are also known to be made by more experienced adventurers and weapon-smiths. The variants are heavier and more expensive by deal more damage and/or provide other magical bonuses.

(The Bashaak is a weapon from the show Stargate SG-1 which is an MGM production.)
